Are the specs of the Viva TC9FD (paper cone) really the same as the TG9FD (fiberglass cone)? Has anyone listened to both and can comment? The photos of the fiberglass variant (like Jhutka's) look really nice compared to black paper.

I believe earlier in the thread the author said they Sim quite differently and He advised the Fibre Glass version be used. I have used the paper cone variety in small closed boxes for computer sound and they are quite good considering the $11 price paid for each.

Looking at the specs on these drivers the fibre glass unit is rated at 10 watts RMS. The alternate is a 20-30 watt device. Reviewers at the Parts Express site say both sound good but the one is handicapped by its low power handling. One reviwer includes a picture of DIY 13litre tower with the paper version installed and gives it high praise!!

I use the paper cone Version in a tml, thanks to the very wide baffel, no correction requiered. The Fiber glass version is supposed to be not better in Sound but more expensive. It does have very differt Tsp parameters.

I tried your flat wall tml design in a stereo setup and really like it. You are right that no BSC is needed (as there is no baffle step). This is a great advantage in keeping costs down as inductors and resistors for $12 driver are a significant expense and rob amplifier power. The paper cone version seems to be a much better buy given the higher power rating and better high end frequency response.

Thanks for the feedback. The tml with the vifa-paper cone is not mine, i just built and liked it. Here is the original thread, preety easy build. You just Need a wall, then no hassle, someone even left the back panel off and put it smack on the wall.
There is Even a closed build if you want to add a Sub.

If you leave the back off and use the wall, how do you brace it? This is a good time to ask does anyone use drywall boards to make speaker enclosures? It is cheap and easy to cut. Provides good damping too?
